SUBSTRATE CONNECTING STRUCTURE

摘要

A substrate connecting structure includes a circuit substrate where an electrical component is installed on the back face, a signal cable into which a plurality of signal transmission lines electrically connected to first signal line connecting portions and to second signal line connecting portions, respectively, are inserted, and a coupling member that is formed by a conductive member including a fixing section disposed at the end portion of the signal cable, a flat section on the front face of the circuit substrate, and a through hole, the coupling member fixing the signal cable and the circuit substrate, wherein the central axis of the signal cable is displaced toward the back face side with respect to the central axis of the circuit substrate.

1. A substrate connecting structure comprising:
a circuit substrate including a front face and a back face opposite to the front face, where an electrical component is installed on the back face; a signal cable into which a plurality of signal transmission lines are inserted, the plurality of signal transmission lines being electrically connected to first signal line connecting portions provided at predetermined positions on the front face and to second signal line connecting portions provided at predetermined positions on the back face, respectively; and a coupling member that is formed by a conductive member including an annular fixing section disposed and fixed so as to cover and wrap an outer circumferential face of a cable end portion of the signal cable, a flat section joined and fixed to a front face of the circuit substrate, and a through hole that is provided between the flat section and the fixing section and communicates between one face and another face of the coupling member, the coupling member integrally fixing the signal cable and the circuit substrate, wherein a cable central axis of the signal cable fixed to the fixing section is displaced toward a side of the back face with respect to a longitudinal direction central axis of the circuit substrate to which the flat section is fixed.
